不少的住宅小 区在设计施工时就全部安装上了太阳能热水器。太阳能热水器一般安装在屋顶上，这样就需要在卫生间与屋面热水器之间 设置冷热水管道，住宅设计时若不考虑太阳能热水器的安装，今后住户安装时只能将冷热管道沿建筑物外墙敷设，这样既 增加住户安装时的难度，增加管线投资，又影响建筑的美观。所以在建筑给排水设计时需要先征求开发商的意见，是否统 一设计，统一施工太阳能热水器；或只预留出太阳能热水器及冷热水管道的安装位置。太阳能热水器的冷热水管道可敷设 在管道井内；不设管道井的住宅，可在卫生间靠近沐浴器的墙角增设一根de110的UPVC排水管作为太阳能热水器热水管道的 套管，在每户卫生间距地面1m处设一个de110×75三通，作为冷热水管的接入口。
（五）空调冷凝水排放问题
近几年，空调逐渐进入千家万户，空调冷凝水无组织排放污染建筑物外墙，已是影响生活区美观的一个重要问题。建筑给 排水设计时应考虑空调冷凝水的有组织排放。具体做法可在预留空调外机位置旁设置冷凝水排水管，排水立管选用PVC－U排水管 de40，在每层空调机高度预留排水三通，便于空调机排水软管直接接入。

The multilevel residential housing is given and drains off water several questions designed
Summary : This text give and drain off water on multilevel residential
housing design supply water the exertion of the tubular product , Way of laying of pipeline, water gauge produce family set up, establishment and air conditioner condensation water of pot-type boiler discharge issue goes on the discussion , And put forward some concrete views.
Keyword: Skyscraper, supply water the tubular product , the pipeline is
laid, The water gauge, the solar water heater The skyscraper is simple with its auxiliary facility, the fabrication cost is low, the characteristic such as being convenient of estate management, Receive the welcomes of the real estate developer and vast resident of small and medium-sized cities very much. How project planning and design of inhabited region, scientific and technological industry of comfortable house, lead the request according to 2000, Improve the design level of the house, build out a comfortable living space for each household, It is each designers duty. As the heart of the house --The kitchen, bathroom, is that the function is complicated, hygiene, safe and comfortable degree are expected much, It is miscellaneous to build, the space expecting much in technology. So, the designer must consider synthetically with the idea and method of global design that the kitchen, bathroom give installation of the drainage pipeline and equipment,etc. . Give and drain off water on skyscraper design supply water exertion, to lay pipeline of tubular product, water gauge produce family set up, establishment and empty of pot-type boiler now Transfer condensation water discharge issue discuss together with colleagues.
( 1)supply water tubular product select problem for use Traditional watersupply tubular product adopt zinc-plated steel tube generally, because zinc-plated steel tube exchange the corrosion, Use short-lived , use for and send domestic water can satisfied with water quality sanitary standard shortcoming, Ministry of Construction is popularizing the application of the feed pipe of plastics energetically . A lot of districts and cities have already expressed regulations: Forbid designing and using the zinc-plated steel tube , use widely the feed pipe of plastics. The plastics supply water In charge of compared with metal pipeline, light, it is fine to able to bear the intensity of keeping, Send obstruction little liquid , able to bear chemistry better to corrode performance, it is convenient to install, The steel energy-conservation of the province, merit of having long performance life etc.. Supply water and use plastics pipeline: Hard polyvinyl chloride( PVC-U), high density
6
polyethylene( HDPE), pay and unite polyethylene( PEX) , modify the polypropylene( PP-R, PP-C), gather butene( PB), aluminium mould and compound and in charge of and the steel is moulded and compound and is managed etc.. Choice of tubular product economic comparative course of technology, technology should from pressure, temperature, environment for use, install method,etc. go on and consider, Combine owners at the same time request and the house of grade,carry on and fix after being consider synthetically technology not economic. The above plastics supply water tubular product can supply water tubular product as house life. The economic and functional house conciliating Strand room in the face of the masses of with low- and medium-level incomes resident, can select for use hygiene grades of hard polyvinyl chloride in charge of as feed pipe mainly, In order to reduce the fabrication cost; Medium-to-high grade commodity apartment available aluminium Mould and compound and in charge of or other plastics supply water the tubular product as the feed pipe. House mix hot water temperature that water order exceed 600 C, so above-mentioned tubular product in charge of except hard polyvinyl chloride and aluminium plastics compound and in charge of( PE-AL-PE), Mostly the tubular product can be regarded as the hot water pipeline of the house.
( 2) pipeline lay problem 1. give and drain off water it set up there arent one that in charge of
1)Will install it in the corner place of the kitchen, bathroom tomorrow. Adopting this kind of way of laying more in the design of house in the past, it is convenient for it to construct, But will reveal the pipeline and hinder the room beautifully tomorrow Watch, the households will mostly be hidden with the light quality material in the equipment two times.
2)Will install it in the overcast angle place of the outer wall of the building tomorrow. Way this suitable for southern weather warm district only, the minimum temperature in winter cant be lower than zero degrees Centigrade, In case water pipe water-logging freeze ice is bloated to split pipeline, influence household use. Pipeline lay in outer wall, influence building to be beautiful, too inconvenient on manage and maintain in the future.
3)Lay it in the pipeline well. This way makes the room clean and beautiful , but the pipeline well has taken up the area of the bathroom, And pipeline construct, maintain relatively more difficult. Bathroom set up concentrate pipeline well, concentrate pipeline on assign in the well feed pipe, drain pipe, This is that the civilized importance lives in the kitchen of comfortable house, bathroom Embodiment. I think : Should consider the establishment of the pipeline well of the bathroom in the medium-to-high grade building conceptual design of commodity apartment, Improve quality of using of bathroom promptly so , can solve hard polyvinyl chloride drain pipe rivers noise heavy problem, Improve the environmental

quality level of the room; Whether for bathroom in the areas for little economic and functional house and Overcome difficulties room, warm area give and drain off water and set up and in charge of and can consider and lay in the outer wall in the South, In order to increase using the space of the bathroom; Pipeline install and in the room, should influence kitchen, bathroom every sanitary equipment use of function tomorrow 2. supply water and prop up there arent tube House supply water prop up and in charge of pipe diameter one ≤ 32mm, de of battle,, little plastics feed pipe of pipe diameter is the crooked state, So the house supplies water and is propped up and in charge of being recommended and adopted and set up secretly. Supply water to prop up to manage darkly There are thes way had:
1)Set up in the brick wall secretly. Wall turn on and in charge of trough in brick when constructing, in charge of trough width tube +20 mm, de of external diameter,, degree of depth tube external diameter de, The pipeline is imbedded and managed directly Trough, and with in charge of card fix in trough of inning charge of son.
2)Whether pipe diameter supply water and prop up and last de ≤ 20mm,can set up at floor secretly piece make level by layer. Turn on and in charge of trough in floor( ground) the board when constructing, it wides trough have to be de +10 mm deeply 1/2 of the de, Half pipeline imbed and in charge of trough, and with in charge of card fix in trough of inning charge of tube. Aluminium mould compound and in charge of and pay and unite polypropylene in charge of pipeline adopt metal pipe fittings connection, Must strengthen and in charge of trough size when adopting and set up secretly, and rivers some flood peak loss relatively heavy. Assign the relative house that concentrated to the kitchen, bathroom interior hygiene utensil, Can adopt and divide Water device go on and join , divide water device whether one more than branch in charge of and connect, every hygiene utensil supply water and prop up and in charge of and connects and publishes from the water dividing device separately. Can already prevent the tube burying the pipeline secretly from being connected like this Permeate the question. Can reduce some flood peak lost, decrease the fabrication cost of pipe networks 3)Drain off water and prop up the tube to lay House room drain off water and in charge of and should set up at the time of inning this each, drain off water and in charge of permeating sideways like this canning prevent the sewage from waiting for the pollutant to enter the neighbor family sideways, Will not influence the neighbor either when the pipeline is maintained Normal life of one. Kitchen wash water drainage of basin propped up and in charge of generallying inserts draining off water to stand to manage this layer of floor sideways; Floor drain drain off water propped up and in charge of laying the room of lower floor. A lot of colleagues think now: Whether kitchen the ground it lay ceramic tile

of,whose name is clean in when need develop with water,not strong in meaning to set up floor drain, So kitchen set up ground floor drain, avoid and drain off water and prop up and in charge of and enter neighbor family sideways already so, Can increase using the space of the kitchen . Bathroom drain off water and prop up and in charge of and lay concrete measure have in this layer sideways inside:
1)Improve the bathroom ground . Ground tendency high 150mm, adopt back row type take stool pot, washing basin, bath tub, water drainage of floor drain in charge of and bury in cushion layer secretly sideways.
2)Adopt the sinking type bathroom. Bathroom sink 350mm the floor, hygiene utensil drain off water and in charge of and bury on sinking space secretly sideways
Two method these can realize water drainage of bathroom prop up and in charge of earths surface to bury underground this one without entering the neighbor family sideways. Bury pipeline when installing, construction quality must check on strictly, can construct bathroom ground after confirming qualified secretly, So as not to leave the hidden danger in giving in the future using. Bathroom ground construct and can pack coal ash light quality material , also can adopt and lay bricks impracticable to lay plate making construct ground, Ground must make waterproof to deal with, method can waterproof to deal with according to roofing, make two oil one rubber and plastic ointment waterproof cloth.
3) water gauge the open air set up problem The water gauge is had indoors, not only the work load of checking meter is very heavy , but also make the security and privacy of the house reduce greatly . So house divide into households of water gauge or divide households of figure of water gauge Show that should be set up in the open air. Skyscraper water gauge the open air set up following several kinds of forms: Whether 1.adopt far it pass by water gauge Change the ordinary water gauge into and pass the water gauge far, is joined the water gauge and data gathering machine by a signal line, And then reach intelligence to manage( the computer). Its merit lies in saving a large amount of people Strength comes to check meter, the data are accurate, the shortcoming is that the fabrication cost is high. Whether 2.adopt magnetic stripe card of by water gauge Users buy the electronic card of the running water Company in advance , then insert it in the storing device of the water gauge, Card amount of money deduct automatically on the water, this way user need to prepay the water rate, The price of the water gauge is relatively high.
3. adopt it set up at the open air water gauge not ordinary
1)The water gauge is set up in the stair have a rest in the alcove of the platform. Household watersupply to prop up and manage and enter the kitchen, bathroom after the water gauge is measured. Way this realize water gauge produce room set up, equivalence low project have , supply water and set up and in charge of and set up with water gauge office results
